Globe Valves

  • High thrust cylinder actuator.

  • Easily reversible and features exceptional stiffness, repeatability, and low hysteresis.

  • Globe-style bodies feature smooth, streamlined, constant-area internal passages with no pockets, permitting high capacity with minimum.

  • Bonnets are designed to permit a wise variety of packing configurations, including a double set of packing, without changing bonnets.

  • ValtekSul offers environmental packing systems as ISO 15848-1, FCI 91-1 or TA-Luft

  • Double-stem guiding located out of flow stream eliminates galling associated with cage guiding self-aligning seat ring.

ValtekSul offers environmental and
non-environmental packing systems.

The non-environmental packing systems also provide goog leakage control, their more simple materials and designs will usually leak at higher levels and will not maintain to long time ultra-low leakage.

The environmental packing systems are designed to provide less than 500 ppm service for typical control valve applications.

The live-loaded packing systems maintain
a constant sealing force within the packing box, providing low leakage performance with minimal field adjustment.

Envoronmental packing systems that have been tested and certified, meeting such standards as ISO 15848-1, FCI 91-1 or
TA-Luft.
